I recently bought an Epson CX9400FAX printer to replace an older one. In the past I have saved a bundle of money by refilling my Epson cartridges. Now I've been told that you can't refill the cartridges for this model as there is some sort of code that kicks in when the cartridge is empty and if refilled still talls the printer it is empty. I've discussed this with refill stores and some say they are working to find a way to overcome this code but I rather doubt they are really trying. In any case, having to buy new cartrides all the time is very expensive. Does anyone have any suggestions?
